Once you've done this, you're ready for the next step: you need to figure out how to remember that accurate sound. Our ears have a short "memory," so they need a constant reminder of what good sound is. I like to use an accurate pair of headphones to listen to a CD before I start tuning my car. That way, I can tell right away what small changes I might need to make in order to perfect the sound. If you have access to a high-end home stereo system, this is a great way to tune your ears as well. The most important thing is to listen to your reference sound right before listening to your car system, with the same music. Get the IASCA or USAC judging CD, since they have many different well-recorded tracks with liner notes that explain what you should be listening for in each one. Both of these discs also give you information on how to acquire the full-length CD's from which the reference tracks were recorded.
Finally, you need to have a way to adjust the sound of your system. Assuming you have spent your money wisely on good quality, well-installed equipment, your system can really benefit from some form of equalizer. Once the system is working correctly with the right crossover settings and amplifier gain adjustments, the equalizer can be used to really dial in the tonal balance of your system. A good 31-band graphic equalizer is probably the best, since it gives you a wide array of adjustments over the whole range of audible frequencies. If you notice a difference in sound between your reference system and your car system, you can play with the equalizer until you make it sound right. It takes some practice to recognize which frequencies affect which instruments, but it is a skill that can be gained with enough practice. The best part is that practicing means listening to your system, and that's what it's all about.
This month's question comes from Ryan, who asked me how he can break into the car audio industry. Most people start out in retail, meaning a car stereo shop. Large retailers like Circuit City are also a great place for car audio enthusiasts to get their start. If you want to take the next step and actually work for a manufacturer, your best bet is to get to know the factory reps when they come to your store. Ask them to keep you informed if any jobs open up at their companies. Almost all of the people in sales and marketing at Alpine started out in retail, so this technique has been successfully tested. Another good idea is to get some education at an installation school or a sales course, so that you have the skills to stand out and get noticed in the industry. As always, send your questions to Sbrown@Alpine-USA.com.
That's all for this month; I'll see you in the lanes.
